ICloud is clobbering my network

I upgraded my iPad, iPhone and Mac to test out the new iOS 5 features this weekend. With one device conected, things were slow. With all three connected, the network was almost unusable, even after 48 hours. I had to decouple a few devices just to get things moving again. Reminds me of the days of Pointcast, when everyone's machine synced simultaneously, causing massive latency.

Anyone had similar experiences?
